Forgot the name of a game? Post here.

I think you might be looking for Legend of Heroes for PSP. Sounds a lot like it.

This is what I thought of as well. Now I don't know this series in general, but the PSP version might also be a remake of a Turbo CD game(I know there was something in this series in English there), just in case it wasn't the PSP(which is kind of new to be forgetting games you played on it......) you were thinking of.

Okay, I have no clue if this game even exists or if I just imagined reading about it, but the idea was so unusual it kind of stuck in my head. Later when I tried to look for it I found nothing.

It was a game that starts out like a horribly traditional RPG, but then you're controlling the one who was playing the game (a kid I think) and the person who was playing the game is suddenly in the RPG world. It turns out that the 'hero' of the game is a jerkass leaving a trail of chaos all over the place and you have to set things right. Kind of a deconstruction of usual RPG elements.

It sounded unusual and I thought I'd check it out. Seems like it was for the PS1, but I'm not sure about that. Ringing any bells?

Aside from the part about the "hero" being the villain, which may be a part of it, this actually sounds like God Medicine, a rom translation for the Game Boy.
